Hello Lorenz, I knew I will not be able to explain my point.
I have one class: Question (What is capital city of Germany)
Another class : Answer (Berlin)
and similar question/answers instances.
I want to show rdfs:comment of answers like Berlin,Madrid and it works
So when I mentioned ?x rdfs:comment ?comment, the ?x contains Answers
like Berlin, Madrid
After this query if I want to show the rdfs:abstract of Answers (Berlin
etc) from Dbpedia endpoint directly, is it possible?
The instances data could be the following in my ontology:
I have one suggestion: Is it possible we are allowed to paste a screen shot
of our ontology or something else in this group like we do in Protege
group?

<rdfs:comment>Berlin, Germany’s capital, dates to the 13th
century. Reminders of the city's turbulent 20th-century history
include its Holocaust memorial and the Berlin Wall's graffitied
remains. Divided during the Cold War, its 18th-century Brandenburg Gate has
become a symbol of reunification</rdfs:comment>
